Kyle Busch clinches Joe Gibbs Racing 1-2 on Phoenix practice sheet
Matt Kenseth vaulted to the top of the speed chart Friday in the first practice for the NASCAR Sprint Cup Series at Phoenix International Raceway.
Kenseth, in his first season with Joe Gibbs Racing, turned a lap of 137.023 mph in preparation for Sunday's Subway Fresh Fit 500, the second race of the season for NASCAR's top series. That speed edged teammate Kyle Busch's 136.976 mph lap by a margin of nine thousandths of a second.
